how long will the sun of our planetary system last?

Answer 1

much longer than we as a species will i think..., i think professor hawkins has classed our sun as 'middle aged' with very little sun spots (black marks) on the surface, this tells us our sun is still in a healthy condition.

Answer 2

Longer than humankind and longer than the innermost planets. In a few million years, our sun will turn into a red giant, expand beyond the orbit of Mars and swallow up that planet and those that orbit even closer to the sun. After another few million years, it will collapse upon itsself. The resulting explosion will be spectacular, called a '"nova". The remnants of that explosion may produce one of the smaller objects known as a neutron star, or it may just peter out fairly rapidly - in astronomical terms, that is. Don't worry - humankind will have been extinct longer than Earth has existed by the time the sun reaches it's red giant state.

Answer 3

No, easily, our universe is thirteen.7 billion years previous, and our photograph voltaic gadget is approximately 5 billion years previous (the Earths is approximately 4.5 billion years previous). Our solar and planets formed from a cloud of gasoline and dirt that have been enriched by exploding stars. besides the undeniable fact that, we don't think of there became into basically one celebrity and planets it formed from, sitting in this maximum outstanding spot, and there is not any information yet for existence exterior the Earth. a celebrity will circulate supernova consistent with it is mass (greater effective than 8 situations the mass of the solar) or if it is 'fed' mass by a binary celebrity and exceeds the Chrandrasakar mass cut back. there is not any Nemesis. it is not technology. Brown dwarf stars at the instant are not left at the back of by supernova, nor can they circulate supernova. i don't be attentive to the place you're getting your 'technology' from, besides the undeniable fact that it is exceptionally lots thoroughly incorrect. I advise attempting a textbook as a substitute next time.

Answer 4

After reading some of the answers, 90% of them could be correct. There isn't anyway of knowing when or how long the sun will last. But I have heard the sun is growing.. as it grows, it will engulf our solar system and then implode. Thus creating a black hole.

Enjoy the life you have, and the time you have left.

Answer 5

Beyond the seventh generation, which is all that needs to concern us at the moment. We have more immediate problems to deal with, such as polluted water, a tattered ozone layer, and generally bad attitude among politicians. Oh, yes, and getting older; we baby boomers feel our age these days, and that's beginning to matter to a lot of younger people, too.

Let's just go on solving the problems as we come to them. Any significant change in the sun is a pretty remote problem.

Answer 6

Our sun will run out of nuclear fuel in 5 billion years, but it will exist as a red dwarf and eventually a white drawf for many billions more.

Answer 7

Science has determined that the sun is about 4.5-billion years old, and that it will continue as a stable star for another 4.5-billion years.

Answer 8

Another 5 billion years or so

Answer 9

more than a 100 billion well you can search on the net maby on yahoo or google or somethin to get the correct answer

Answer 10

The last estimate I saw claimed it will die in 5.8-6.2 billion years. On the bright(sic)side,,we won't know nor care,,;-)=
